SAD-IRON.

Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed May 11,1906. Serial No. 316,239.

To all whom it may concern:

Be it known that I, JOHN J. LUCAS, a citizen of the United States,residing at Belleville, in the county of St. Clair and State ofIllinois, have invented certain new and useful Improvements inSad-Irons, of which the following is a specification.

My invention relates to sad-irons and consists in the construction andarrangement of the parts which will be more fully hereinafter described,illustrated in the drawings, and particularly pointed out in the claims.

One object of my invention is to provide a sad-iron in which the heatingcore shall be inclosed in a separable shell composed of two parts, aninclosing shell and a smoothing plate, which shell and plate may bereadily secured together, or detached from each other by convenientmeans.

A further object of my invention is to provide means for attaching anddetaching the inclosing shell and smoothing plate quickly andeffectively.

A still further object of my invention is to provide means forinsulating the handle from theY heating core, and thereby rendering thesame cool to the grasp at all times.

I accomplish these objects by the mechanism shown in the accompanyingdrawings forming a part of this application in which like letters relateto similar parts.

Figure 1 is a side elevation of the sad-iron complete and ready for use.Fig. 2 is a longitudinal vertical section of the sad-iron with all ofthe parts in place. Fig. 3 is a rear end view of the sad-iron showingthe swinging lever in place and means for holding-the inclosing shelland the smoothing plate securely together. Fig. 4 is a perspective viewof the heating core showing a llifting-bail for removing same, andsecuring tongues for holding the same firmly to the smoothing plate.Fig. 5 is a perspective view of the smoothing plate showing a block andscrew bolt for securing and holding the inclosing shell by the swinginglever, and cleats for securing the tongues on the heating core andholding the same firmly in place.

Referring to the drawings A represents the inclosing shell, B thesmoothing plate, O the handle, D the swinging lever, and E the heatingcore.

The inclosing shell A and the smoothing plate B are made in the generalshape now common in sad-irons, and are, preferably, cast of suitablemetal and afterwards nickel-plated or otherwise given a high polish.

The handle C is formed in the shape shown in Figs. l and 3 and issupported on the inclosing shell A by short posts a a secured to the topof said shell and by the bent arms a a/ of said handle. The posts a aare of such length that they will raise the handle G a short distanceabove the shell A for a purpose hereinafter mentioned.

The top of the shell A is formed so as to providea heat insulatingchamber c in the top of the same. In

said chamber c is secured heat insulating material c, preferably sheetasbestos, in the form of a slab of the general shape of the interior ofthe shell A; said slab held to the under side of the top of the shell bybolts, c c, as shown.

The handle C, preferably made of a poor heat conductor, such as wood, isconnected by thin metal arms a and posts a to the shell A. Because theseposts are relatively small and therefore have relatively small heatconductivity, and becausev of the provision for free circulation of airbetween the shell A and the arms a/ and handleC, and because also of thelow heat conductivity of the handle itself, said handle may be-graspediby the operator without danger of burning, no

matter how hot the shell A may be.

The smoothing plate B, as heretofore stated is preferably made of castmetal and either nickel-plated or given a high polish as above stated.

It is so shaped that the inclosing shell A will readily fit just insideits upper edges as shown in Figs. 1-3-& 5. To the rear end of said platea block B is formed, preferably cast as a part of the plate, in theupper part of which a screw-bolt is secured for a purpose herein aftermentioned.

At the front of plate B is a lip B projecting upward and backward, andadapted to receive between it and the base of said plate B the lip A/ofthe shell A. By means of the engagement of this lip A/ with lip B, andthe engagement of the latch D, hereinafter mentioned, with thescrew-bolt b of lug Bf, the casing or shell A is removably secured tothe plate B.

Inside ofthe smoothing plate and near the forward end cleats b b areformed to receive tongues e e on the heating core E.

The swinging lever I), is loosely pivoted to the inclosing shell A, atits rear end and near the upper part by a screw-bolt d. It is made of apiece of fiat metal and has a hand-piece, preferably made of wood. Atits lower end it has a side notch df which in operation is adapted toinclose a screw bolt b in block B. The function of this swinging leveris threefoldg-rst, it effectively and vinstantly secures the inclosingshell and the smoothing plate together,-second, it releases them quicklyand perfectly ',-third, it produces a pressure on the rear end of theinclosing shell which forces it forward, carrying the heating core withit and thus firmly locks all of the parts together.

The heating core E is formed, preferably of cast metal, in the form ofthe inclosing shell A, and the smoothing plate B, and of such length anddepth as to loosely fit within them. It is provided with a lifting baile by which and suitable tongues or levers, it may be deposited in aheating furnace to be heated, and after being heated may be lifted outand placed on the smoothing plate oi the sad-iron, and then inclosed inthe shell for service.

In operation it is proposed to use several of said heating cores so thatone or more of them may be in the process of being heated While one maybe in use.

With the foregoing description, taken in connection with the drawings itis believed that the operation of this invention will be fullyunderstood by any and all persons desiring to use it.

Having thus fully described my invention, what I claim and desire tosecure by Letters Patent is:

1. In a sad-iron, the combination with a case comprising a shell andsmoothing plate separable from each other and provided with lockingmeans for holding them together', of a heating core adapted to be placedwithin said case; said case and core provided, the one withhorizontallyprojecting lugs, the other with corresponding recesses,whereby the core and case may be inter-locked.

2. As an article of manufacture, a sad-iron comprising an inclosing`shell, A, provided with a heat insulating chamber, c, having a slab ofheat insulating material, c', secured in said chamber, a smoothingplate, B, a heating core E, a handle C, supported on said inclosingshell, a

l swinging latch D, pivoted to the rear end of the shell A,

and a pin b at the rear end of the plate B, for engagement, and forsecuring the shell A and the plate B together; and tongues ee on thecore E, and cleats b b on the inside of the smoothing plate B forlocking said core and plate together, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
